This big boy is the American Lobster. A rather big crustacean with big pincers and a strong tail. They are found in the Atlantic coast of North America mostly and travel the seafloor in search of food. In rare cases, it's possible to find a blue lobster, and sometimes a yellow lobster. These lobsters mate after the female has molted and her exoskeleton is still soft. The lobster hides underneath rocks to escape predators.
